There's also been news on the Xiaomi Mi Band 2 launch and Fitbit's heart rate accuracy has come under serious scrutiny.

Read on for the big headlines of the week...

Pebble's new smartwatch duo

Pebble is still acting like a bedroom startup by launching its new products onto Kickstarter, despite selling hundreds of thousands of devices in the last four years.

The latest connected timepieces to need crowdfunding in order to become real products are the Pebble Time 2 and the Pebble 2, the follow ups to, you guessed it - the Pebble Time and the original Pebble.

The former is being touted as a "premium smartwatch for the active professional" and is stainless steel with colours available in gold, silver and black.

It packs an optical heart rate sensor; as does the all new base-level Pebble, along with the ability to intelligently track sleep and step counts thanks to the built-in accelerometer.

The Pebble that's not a smartwatch at all

It wasn't all Pebble smartwatch news though. The company also revealed its first non-smartwatch by way of the Pebble Core, a GPS tracking wearable for runners with no display that can store up to 4GB of music and stream Spotify via 3G.

My, how things have changed. Pebble announced its Health platform last year, bringing native activity and sleep tracking to smartwatches. Now we have not one, but three fitness focused wearables.

Fitbit missing a beat (or 20)?

We followed that up by speaking to not only the lawyers involved but the scientist who carried out the study. It's not great reading for Fitbit - check it out right here - with the argument being that not only is the heart rate tech inaccurate, but also dangerous.

Xiaomi Mi Band 2 incoming

The Xiaomi Mi Band 2 has an official release date. The 24/7 activity tracker is going on sale on 7 June - the Chinese company's CEO spilled the beans at an event this week.

We've already had a glimpse at the Mi Band and Mi Band Pulse successor recently after it was shown off at Xiaomi's Mi Max smartphone launch.

Of course, this isn't the only new wearable we're expecting to from Xiaomi: a Mi smartwatch should be launching in the next couple of months.

Crowdfund this

The focus of this week's crowdfunding bunch was Pilot, which has obliterated its $75,000 target already. That's not surprising given that the real time translation earpiece uses speech recognition and machine translation to translate a host of different languages.
